I have just watched the DVD of Harry Potter and the Goblet of Fire. I thought it very well done. My usual complaints that the music was too loud, muffling the dialogue, and everything was too dark to see properly applied, but I turned the subtitles on and was able to follow it.
The young actors have much improved since the first film, Ralph Feinnes was excellently evil, but Michael Gambon is still a disappointment after Richard Harris. Brendan Gleeson was fun. Spotting the uncredited actors was interesting. No John Cleese this time, but veteran comedian, Eric Sykes put in an appearance at the beginning and the new Dr Who, David Tennant played the part of the villain, Barty Crouch Junior.
